Try hog root. In Germany hog root is used in several Jäger type or krauter herb liquors and imparts a strong herbal flavor. It is great for digestion too. If you're ever at a liquor store and see schwartzhog pick up a bottle and give it a taste to see what it's like. I'd be really curious to see what a wine made from say, ginger, wormwood, and hog root would be like.
